Rear Finish Mower Woods rear mower gearbox

bihawkbandit · Jun 28, 2019

Hello
Got a Woods RM660 mowing deck from an auction. Turns out the shaft has a bad gear / broken cog in the gearbox. Looking around what makes a finish mower gearbox different from a brush hog? I see universal gear boxes, but they all say brush hog. A new Woods brand gear box far exceeds making it worth it. What are my repair options? Or do I have a 3 point paper weight?

My guess is the ratio, I am thinking a finish mower spins faster than a brush hog.
Have you checked for replacement parts? Or only sold as complete gear box?

The gear is $980.83 and the shaft is $347.04 Woods RM66� Rearmount Finish Mower Parts Diagrams
The whole gear box is $1,737.44

Yeah, that’s kind of a show stopper.

Here's another used one from North of you. Depending what you have in yours it might be worth looking at this one. Woods rm 66 3pt finish mower - farm & garden - by owner - sale

From what I could find it looks like a 1.76-1 ratio gearbox. If the ratio was right or close enough and it fit, wouldnt matter what the gearbox was for.
